In a freak accident (while the mane six is on vacation to manehattan), Discord decides to twist space and time itself on April Horseshoes Day; meanwhile, the Vortex returns to destroy the Tides of Time in an attempt to lock Ecco in the Tides forever, giving them the chance to strip Earth of all its living inhabitants once again. The result? Twilight is warped to an ancient Earth, and Ecco is warped to Equestria. Can the mane six discover what has happened and get Discord to stop? Can Twilight survive the Vortex in a dark game which is virtually impossible to win? In the end, one thing is for certain - Ecco cannot bear Twilight Sparkle's element of magic to stop Discord, and Twilight Sparkle wasn't programmed to get retries for the levels in Ecco the Dolphin III's source code...

"You take the cover of two different disc holders. One is for a strangely unreleased MLP episode, and the other is a snatched Ecco the Dolphin III demo playthrough. The person who gave them to you told you to play them both at the same time on your computer, and line them up so that both CD's would hit 13:13:13 in their running times. He seemed a little weird, saying that through ahead-of-its-time quantum physics, dimensions could be crossed if the conditions were right - but for a strange reason, he didn't tell you who he was - he just told you that he wanted you to test the theory for him, because if he revealed his true identity, it could make serious headlines on the news and his career as a quantum physicist could be kaput. Having nothing better to do one Saturday night, you take the two discs, and slide them into your computer. But first, you read the descriptions on the back of their covers:

MLP:FIM-SEASON#EPISODE# "TWILIGHT'S MULTIVERSE THEORY MELTDOWN"
